Answer:
The minimum number of rolls to buy is 9
Explanation:
step 1
Find the perimeter of the ceiling of Katie’s living room
The perimeter of a square is equal to
where
b is the length side of the square
we have
so
step 2
Find the length side of the diagonals of the ceiling
Applying Pythagoras theorem
step 3
Find the total crepe paper needed
Sum the perimeter plus two times the length side of the diagonal
step 4
Find the number of rolls needed
we know that
Each roll contain 10 ft of crepe paper
so
Round up
The minimum number of rolls to buy is 9
doubling the radius will have a greater effect
v of cylinder=pi x square of radius x hieght
lets take an example,r=2,h=2
v=8pi
doubling the hieght,h=4
v=16pi ie twice the initial volume
doubling the radius,r=4
v=pi x 16 x 2
=32 pi ie four times the initial volume
therefore radius makes a bigger difference
Answer:
Geologic process: Volcanism.
Geographic features: big island of Hawaii, smooth surfaces of the lunar maria, Mars's Olympus Mons.
Geologic process: Impact cratering.
Geographic features: old surface features of the lunar highlands.
Geologic process: Erosion:
Geographic features. Earth's Grand Canyon.
Geologic process: Tectonics.
Geographic features current locations of Earth's continents, Mars's Valles Marineris, Mercury's many long, tall cliffs.
Note that all four processes are interrelated, so although one may be major to a particular feature, others also play some roles in their formation.
